Television’s History channel explored the story of America to great success nearly two years ago. Now it is setting its sights even higher.

The network says a 12-hour miniseries, “Mankind the Story of All of Us,” will debut late this year in the nearly 300 million homes where the channel is carried worldwide. It will be the first time the network has offered different versions of its programming to different parts of the world.

The new series traces the development of man from the Big Bang through epochal events like the creation of tools and development of agriculture.

The series “America the Story of Us,” which aired in spring 2010, was the network’s most-watched special ever.
